Funny you have trouble with Ogon, Lynn. I have some that has been out there for several years now. The thing with Ogon is, it never looks as good as when you first planted it. So if you want to use it for say, an accent in a container, you may want to replace it every year. I think it is well worth replacing when used like that.
I noticed that my Fine Leaf Gold is still hanging in there too. Not much of it, and it has partially reverted to dark green (which Ogon also does if you have it long enough to notice it).
